I have never had a worse dining experience in my life. I ordered 2 turkey dinners. When delivered, they were missing the... dressing and bread. I called the store and spoke to the manager. He laughed at the situation and refused to provide themissing items. I will NEVER eat food from ANY Denny's ever again. Read more

Good breakfast...fruit bowl, eggs, bacon, home fries. Ordered biscuit and gravy...gravy was good...biscuit wasn't a... biscuit...not sure what it is now. Our very nice waitress told us they stopped making regular biscuits and that they had becomethe number one complaint of customers. Just an odd thing, won't keep us from going there again. Read more

Food was cold. Coffee also. The bacon was the smallest pieces I've ever been served in a restaurant. Didn't get asked if we... needed refills. Only came because I had a coupon. Next time, IHOP all the way. Read more
